Which of these is an advantage of the SIMPLEC algorithm over the SIMPLE algorithm?

(a) No over-relaxation

(b) No under-relaxation

(c) No undershoots

(d) No extra terms

The question was asked during an interview.

My query is from Incompressible Flows topic in portion Incompressible Flows & Compressible Flows of Computational Fluid Dynamics

Best answer
Correct choice is (b) No under-relaxation

To explain: In the SIMPLE algorithm, the whole momentum equation is used. So, for the correction of pressure and velocity, an under-relaxation factor is used. But, as the SIMPLEC algorithm omits all the insignificant terms in the momentum equation, this under-relaxation becomes unnecessary.
